The new men's Patagonia Light Flyer Jacket uses GORE-TEX® Active fabric to create our lightest, most breathable wind- and waterproof shell for running and cycling. It’s cut to a slim fit and has articulated sleeves, a very slight drop tail, a self-fabric stand-up collar that’s lined with lightweight mesh, a low-profile drawcord hem and a compact lower-back pocket that holds a couple of gels for bonk prevention. Upper-arm zippers facilitate air flow to the always open (yet protected) back vent, and extra-coverage cuffs help warm the hands on 35-degree days while also folding out into mittens if it gets even more frigid. With a Deluge® DWR (durable water repellent) finish, and a reflective logo on the left chest and center-back neck.
